The Earth will soon be traveling through the stream of debris left behind by Halley’s Comet, providing the annual sky show called the Orionid Meteor Shower. This usually reliable meteor shower is expected to peak this coming weekend, October 20-21, 2012, and should produce about 25 meteors per hour, according to the McDonald Observatory at The University of Texas in Austin.
